I'm not so sure I buy into all the hype over radio manufacturers competing for the lowest latency on their systems. All these radio manufacturers are claiming to have a latency of anywhere between 20ms on the older systems down to just a few ms on the newer faster systems. Now look at the average human reaction time which is about 150-300ms. The latency caused by the radio system is very small compared to how much time it actually takes you to react and respond. If you want to be a better driver practice your reflexes and try to train for better reaction time. The speed of the radio is far less significant.
